Lỗi biến tần KEB
| Display | Description | Fault cause and solution |
| conn | Serial Com. Established | Position values are being transferred to the encoder, encoder and serial interface are working. |
| EncId | Unknown encoder ID | Encoder is an unknown type and does not support the required serial communication protocol. Encoder is the wrong type, i.e. EnDat connected to a HIPERFACE feedback card. Solution: verify encoder type. |
| bdCbi | Cable break. inc. channels | The interface looks at each incremental channel for the idle voltage value of 2.5V with reference to common (pin 13). If this voltage is not present an error will be triggered with this fault code. Solution: check all signal connections, replace cable with new. |
| bdCba | Cable break. abs. channels | The interface looks at each data or clock channel for the idle voltage value of 2.5V with reference to common (pin 13). If this voltage is not present an error will be triggered with this fault code. Solution: check all signal connections, replace cable with new. |
| PoSde | Position deviation too high | The position deviation between the incremental channels and the absolute values is greater than 2.8 degrees. On SIN/COS the comparison is made between occurrences of the zero pulse. Too many or too few counts between the zero pulse will trigger this error. Normally, this is caused by a bad encoder cable and/or poor shielding and grounding of the cable. Solution: replace the cable. |
| BdPPr | Enc. ppr does not match | Compares the internal value of ppr stored inside the encoder with the setting of LF.2. If they do not match this error code will be activated. Solution: verify correct encoder ppr and enter it in LF.2. |
| BdInt | Interface Card not recognized |
The serial interface card is not recognized by the main CPU of the drive. Replace the feedback card. |
| bdSuP | Bad internal enc. supply | The internal power supply of the encoder has failed |
| OHEnc | Encoder over heat | Encoder temp is measure by the encoder and the error is passed on to the drive via serial com. |
| OSEnc | Encoder over speed | Actual speed has exceeded the max speed of the encoder. |
| ErEnc | Internal encoder failure | Internal encoder signals are incorrect or out of tolerance. Replace the encoder |
| ErEnc | Internal encoder failure | Replace encoder |
| FrtEn | Formatting the encoder | The encoder will be formatted according to the prescribed structure. This will allow further read/write cycles to occur. |
| nEEnc | New encoder found | The feedback card has recognized that a new or different encoder is now connected to the drive. Therefore it is necessary to confirm. Reenter the values in LF.26,LF.2,LF. |
| noFrt | Encoder memory not formatted |
Encoder memory structure is not valid and therefore can not be read |
| EncBS | Encoder is busy | The encoder is busy during data transfer and cannot accept the transmission. |
| OFF | No com to Enc. Card | There is no communication between the encoder and the drive. |
